We propose a vertex-centric distributed resource orchestration algorithm for finding all feasible mappings of a service function chain in multi-domain networks. Simulation results show superior efficiency and scalability for computing large service function chain requests.
Computation of service function chains in multi-domain networks is critical for enabling the wide deployment of network function visualization for providing end-to-end network services. In this paper, we present a vertex-centric distributed orchestration framework for multi-domain networks, in which physical infrastructure information is maintained locally within each domain without infrastructure...
Mobile sink plays a pivotal role for data collection in wireless sensor networks (WSNs). But, sensor nodes close to mobile sink are bound to change their routes to Base Station(BS) or mobile sink frequently. As a result, they will generate excessive energy consumption of sensors and cause a very large delivery delay. In this paper, an energy-efficient mechanism for data collection based on single...
In this paper, we study the minimum failure resource allocation (MFRA) problem of allocating virtual machines (VMs) across multiple optically interconnected data centers (DCs) with the objective of minimizing the total failure probability based on the information obtained from the optical network virtulization. We first describe the framework of resource allocation, formulate the MFRA problem, and...
In this paper, we study the reliable resource allocation (RRA) problem of allocating virtual machines (VMs) from multiple optically interconnected data centers (DCs) with the objective of minimizing the total failure probability based on the information obtained from the optical network virtulization. We first describe the framework of resource allocation, formulate the RRA problem, and prove that...
In terms of double-controller design technology and relay feedback identification method an autotuning IMC structure with two degree of freedom (TDF-IMC) is proposed in this paper. The model parameters of the controlled process are identified via a modified relay feedback identification method. The setpoint tracking IMC controller and disturbance attenuation IMC controller are designed, respectively,...
